Hanger

HANGER Filed July 27, 1936 Patented June 14, 1938 UNITED STATES PATENT OFFICE 1 Claim.

This invention relates to suspending means and more particularly to means for suspending relatively long sectionalized members through a relatively open space for both assembly purposes and later permanent installation.

In the running of wires and cables for carry-- ing the power needs for buildings it has become substantially universal practice to run hollow pipe sections usually referred to as conduits, which sections are connected together to provide the necessary length, the section lengths being usually ten feet. Through these conduits are run the necessary wires for the given service and at desired intervals provision is made for outlets through junction boxes. Frequently, especially in large factory installations, it is necessary to make a long run of several sections that must be suspended through space. In order to place the pipe lengths in the proper position a cable is stretched between the two points between which the conduit is to be run, which is called a messenger cable, and then some means is used to hold the pipe lengths to the cable until they are secured together and then firmly fastened to the messenger cable.

Heretofore the various means utilized have required in themselves the use of one hand of the person hanging the pipe and therefore are difficult to manipulate.

It is therefore the object of my invention to provide a suitable hanger for the above purpose that will leave the operators hands free during assembly and is simple to use.

With the above and other objects in view which will be evident as the description proceeds, my invention resides in the construction described in the following specification and claim. and illustrated in the accompanying drawing, in which;

Figure 1 is an end elevation of my invention in assembled position, the messenger and conduit being shown in section.

Figure 2 is a side elevation of my device.

Figure 3 is an enlarged perspective view of one half of my hanger, and,

Figure 4 is a bottom view of my hanger.

The hanger of my invention is formed of two complementary parts, 2 and 4, of stamped metal. The sheet before forming is substantially rectangular and the two ends thereof are cut on a substantial angle to the major axis in opposite directions as shown at 6 and 8 on Figure 3. Intermediate the two ends the members are pressed inwardly and upset to form shoulders l and the portions toward the ends from the shoulders are curved on the major axis of the member and form two hooks I2 and I4 of different diameters. Due to the fact that the ends are cut on an angle, the end portion tip extends more than 180 around the end of the circle forming the end.

Between the two shoulders I0 an opening I6 is drilled. The other half of the hanger 4 is an exact duplicate of that first described and when the two are placed together the tapering ends match to form a plurality of spaced circular portions of different diameter and through the upper or 10 smaller of which the messenger cable I8 is adapted to run and through the lower the conduit 20 is adapted to be carried. A bolt 22 fits through the two openings IS in the halves and a nut 24 when tightened holds the two halves in assembled relation, the shoulders I!) strengthening the portions adjacent the force applied by the bolt to provide a more rigid structure. It might be mentioned further that the nut abuts the curved lower portion which prevents it from turning and becoming loose.

As before mentioned and considering a vertical center line through the hanger shown in Figure 1, it is obvious that each of the ends of one half extends more than 180 due to the taper, the center line cutting the half at the approximate middle of the tapered end and the point extending on around the circle. This also is true of either half.

In its use therefore the messenger cable is strung up in its desired position; then a plurality of hanger halves are hung therefrom by the upper half; the conduit length laid in the lower half and will then be supported in place. The operator thus has both hands free to secure tools or other parts and may then apply the other halves and tighten the bolts therethrough.

The hangers may also be applied in their assembled relation by having the bolt partially tightened, one half at right angles to the other. The vertical half may then be hooked over the messenger cable; the conduit laid in the lower half; the horizontal half rotated 90 to align with the first half and the bolt tightened to make a rigid assembly.

Therefore I have provided a hanger which in its partially assembled condition will support a conduit on a messenger without assistance and which may then be fully assembled easily to make a rigid, rugged assembly.

I claim:

In a device of the class described, two complementary members formed of fiat strip material, a straight center portion, two end portions on each strip curved in the plane of the least dimension, the length of the curved end varying across the width of the strip to mate with the complementary member to form two separate circular openings of difierent diameters by the assembly, flanged edges on the center portion'butting together when the members are in juxtaposition to act as spacing means, means passing through the center portions and through the aperture formed by the flanges to secure the two together, said means including a bolt whose head abuts the curved end portion to lock it against turning.
